Title:
METHOD FOR PRODUCING CATALYST, CATALYST, AND METHOD FOR PRODUCING METHANOL
Document Type and Number:
WIPO Patent Application WO/2023/074051
Kind Code:
A1
Abstract:
The present disclosure suppresses deterioration of catalytic activity over time. A method for producing a catalyst according to the present disclosure includes: a contact step (S1) for bringing a copper-and-zinc-containing solid, at least one metal element, and a chelating agent into contact with each other; and, a calcination step (S2) for calcining the solid obtained by the contact step.
